Your feet

These miracles of nature allow us to stand, walk and jump unrestricted. Your toes are made up of 14 bones, two in the big toe and three in the smaller ones.

The five bones in the middle of the foot and your ankle allow you to raise and lower the front of your foot at the sphenoid bones and the cuboid bone.

This is where the scafoid bone, anklebone and the strong heel bone meet.

The bones are protected from excess pressure by muscles and tendons. Crucially, this padding assumes a protective function in certain places - not everywhere.

On natural ground the body weight is dispersed evenly across a surface - however, on hard surfaces the foot only touches the ground at three points.
